Quote from Barlow >>

It was a wonderful campaign and my only regret was not making Grishkar more of a damage-dealer. I do think it was wonderfully fitting that Martha had ultimate goals to fight Grishkar and I drew Martha to kill by chance. I was too late to respond before everyone moved on, but the acid bomb suicide may have been a good time to take Kia's eye since the save was failed (I thought of anyone, she would succeed).

Grishkar also planned to free Bors from the painting and spend the time within the maze to convince him that Martha and Briella were hinderances that held the keys to his rulership and conquest of the new land. Kia and Imryll could be useful if the crusade was presented as righteous. Grishkar would ultimately flex his Lawful Evil muscle and act as Bors' army-builder/enhancer while developing an underground army of neophytes and undead to rise up and take Barovia for Nerull. 

Ooohh modify that a bit: Grishkar would try to pervert Bors' perspective and bring him under Nerull's machinations. When Grishkar makes the move for Lichdom, he would try to convince Bors to ascend into a Death Knight as well.

On Kia’s eye, yeah I screwed up on that save. She had the monk Evasion feature by then that would have given her half damage even on a failure. Once I figured it out I just let it go, since it hadn’t actually killed her. She’ll have to lose her eye another way. :)
